All Sky Imaging: The “Prototype All-Sky Imager” (PASI) is an operational backend developed by Jake Hartman (most recently of JPL), Greg Taylor (UNM), and folks at Los Alamos National Lab. PASI uses LWA1’s TBN output to make sensitive narrowband (~70 kHz) bandwidth all-sky images every few seconds. Real-time PASI output can often be found on LWA TV.

Dark Ages Cosmology: LEDA: The Large-Aperture Experiment to Detect the Dark Ages (LEDA) is a collaboration between Harvard (PI: Greenhill), U.C. Berkeley (PI: Werthimer), UNM (PI: Taylor), and VT (PI: Ellingson) to detect 21-cm emission from neutral hydrogen in the intergalactic medium about 100 million years after the Big Bang (redshifts 20-30), using LWA1 with an alternative digital backend (a full-bandwidth “all-dipoles” correlator) with some additional “outrigger” antennas.
